Abstract

Abstract:

In this study, we investigated the application of liquid-core starter microcapsules in yogurt. Cell density,
fermentation time, the strength and rupture of liquid-core microcapsules, milk dilution and sensory evaluation of
fermented milk were studied during continuous inoculation of milk. The results showed that as the continuous inoculation
time was prolonged, cell density, the strength of liquid-core microcapsules, the dilution ratio of milk and sensory
evaluation scores of ferment milk were decreased; the breakage rate of microcapsules was increased and the fermentation
time of milk was prolonged. In industrial yogurt production, the continuous inoculation time of liquid-core microcapsules
should be 24 days.

Key words: liquid-core microcapsules, continuous inoculation, stability
